BRAKE-SHOE HOLDER.

Specification of Letters Patent.

Application filed June 11, 1909.

Patented Feb. 1t, 1910. Serial No. 501,555.

To all whom "it may concern:

Be it known that I, GEORGE WV. MAPLES, a citizen of the United States,residing at Boaz, in the county of Christian and State of Missouri, haveinvented certain new and useful Improvements in Brake-Shoe Hold ers; andI do declare the following to be a full, clear, and exact description ofthe in vention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to brake shoe holders and the object of theinvention is the provision of a device of this character which may bereadily attached to a brake beam or which may be attached to the brakebeam block which is secured within the cuff. In one form of theinvention, the attachment is secured directly to the brake beam while inthe other form it is secured directly to the brake beam block.

A further object of the invention is to provide a simple, cheap andefficient device of this character which will securely hold the shoes inposition and which will permit their removal and renewal with ease andrapidity.

In the drawings, Figure 1 is a perspective view of a brake block removedfrom the beam with the wear shoe partially inserted in the attachment;Fig. 2 is a side elevation of the blocks showing the locking lever inlocking position; Fig. 3 is a top plan view of the device showing thebrake beam broken away; and Fig. 4 is a perspective view of a modifiedform of the device showing an all metallic shoe holder.

Referring more particularly to the drawings and especially to Figs. 1 to3, l repre sents the end of an ordinary brake beam which has securedthereto the usual block attaching end 2, in which is positioned thebrake block 3. In ordinary use of brakes for vehicles, the block 3 hasheretofore been applied directly to the wheel or a shoe has been tackedto the brake block and used until worn out. This manner of supplyingshoes was very inconvenient and took considerable time. In order toavoid these difficulties, I have attached to the upper and lowerportions of the face, brackets 4 and 5, each provided with central,horizontal slots 6, which are adapted to receive the securing bolts 7,whereby the brackets may be adjusted transversely of the blocks in orderto accommodate the device to vehicles having different treading gages.The lower bracket comprises a supporting table 8, which is formed of onesheet of material and has downwardly projecting reinforcing pieces 9,011 either side thereof. These reinforcing pieces have tongues 10,projecting upwardly above the table 8. The tongues are bent inwardly asshown so as to prevent disengagement of the wear shoe, which rests uponthe table 8. The upper bracket 5, consists simply of a flat sheet ofmetal with outstanding ears having downwardly projecting, inwardlyturned tongues 13, which overhang the block 11 and act to hold the samein position. Upon the outer side of each bracket, there issecured to thecars 12, and the reinforcing piece 9, the arms 14, which extenddownwardly and upwardly, respectively, and act to prevent lateraldisplacement of the shoe 11. Pivoted to the opposite reinforcing piece9, is a swinging latch arm 16, which is provided at its upper end with ahook portion 17, adapted to engage over the ear 9 vertically above, soas to prevent lateral displacement of the arm. Secured to the outer faceof the arm, adjacent the hook portion, is a spring catch 18, whichpasses through an aperture in the arm and enters an aperture 19, in thecar 12. This looks the device in latching position and prevents thedisplacement of the shoe, it being securely held between the arm and thelugs or arms 14.

In the modification shown in Fig. 4, there is shown an all metallicbrake block shoe holder which comprises a back plate 20, having acentrally depressed portion 21, with a raised channel part 22, formedtherein. This channel portion is adapted to receive the brake beam andis provided with a horizontal slot 23, to adjustably receive theattaching bolt.

The lower portion of the block holder is provided with a blocksupporting table 24, and retaining lugs or ears 25. The usual retainingarms 26, are connected to the upper retaining lugs 27, and the pivotedlatch arm 28, is pivoted as heretofore described to the reinforcingmembers of the table 24.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, What I claim is A brake shoe holdercomprising a support, a shoe supporting table thereon, lugs projectingfrom said support to maintain the shoe in place on the table, means toprevent lateral displacement of the shoe in one direction, a swingingarm pivoted to one of said lugs and adapted to engage another lug toprevent lateral displacement in the opposite direction and means to lockthe arm in latching position.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
